Section 13 Serial Communication Interface
13.2.7
SSR is an 8-bit register containing multiprocessor bit values, and status flags that indicate SCI
operating status.
The CPU can always read and write SSR, but cannot write 1 in the TDRE, RDRF, ORER, PER,
and FER flags. These flags can be cleared to 0 only if they have first been read while set to 1. The
TEND and MPB flags are read-only bits that cannot be written.
SSR is initialized to H'84 by a reset and in standby mode.
